1 Cup to Grams
Answer
125 g
1 US cup of plain flour is 125 grams. This is the flour answer specifically — a cup is a volume, not a weight, so the gram figure changes completely for denser ingredients like sugar (200 g) or honey (340 g).
1 cup × 125 g (flour, per US cup) = 125 g
Plain flour

FAQs
How many grams is 1 cup of flour?
1 US cup of plain (or self-raising) flour is 125 grams, using the standard 125 g per US cup.
Why isn't 1 cup always 125 grams?
A cup measures volume, not weight. Different ingredients pack differently — honey is roughly 2.7x denser than flour by volume, so the same cup measurement gives very different gram amounts depending what's in it.
Is this a US cup or UK cup?
US cup (236.6 ml). Most modern UK recipes that use cups mean the US measurement — the old imperial UK cup (284 ml) is rarely used today.
